It doesn't exist as in Eclipse, but you can format your code on commit, and the shortcut ctrl+alt+L will allow you to format easily your code.
After a time formatting the code will be a reflex and you won't even think about it.

• Intellij reformat on file save

You may use a Macro to simulate save actions:

Edit --> Macros --> Start Macro Recording

==> now execute all actions you need (e.g. reformat, rearrange, optimize imports)

Edit --> Macros --> Stop Macro Recording

Give your new Macro a name. You can also assign a shortcut to your macro. Just enter it's name in the settings search and you will find it under Macro.

Have fun!
